Title:
METHOD FOR TERMINAL TO RECEIVE PHASE TRACKING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE SUPPORTING SAME
Document Type and Number:
WIPO Patent Application WO/2018/182248
Kind Code:
A1
Abstract:
The present invention relates to a method for a terminal to receive a phase tracking reference signal (PT-RS) in a wireless communication system, and a device supporting same. The present invention can provide a method and device for determining the frequency density of a PT-RS on the basis of a bandwidth allocated to a terminal, and then receiving the PT-RS through a resource block determined based on the determined frequency density of the PT-RS and a new resource block index for an entire resource block allocated to the terminal.
